Kinematic analysis and membership status of TWA22 AB

Abstract

Context. TWA22 was initially regarded as a member of the TW Hydrae association (TWA). In addition to being one of the youngest (≈ 8 Myr) and nearest (≈ 20 pc) stars to Earth, TWA22 has proven to be very interesting after being resolved as a tight, very lowmass binary. This binary can serve as a very useful dynamical calibrator for pre-main sequence… (More)
